|
|
Yosys is a framework for RTL synthesis tools. It currently has
|
|
extensive Verilog-2005 support and provides a basic set of
|
|
synthesis algorithms for various application domains.
|
|
Yosys can be adapted to perform any synthesis job by combining
|
|
the existing passes (algorithms) using synthesis scripts and
|
|
adding additional passes as needed by extending the yosys C++
|
|
code base.
